If you're still interested, I visited the gravesite of Vincent and Eleanor Lane McCoy today, in Fulton County, Indiana. It's a small cemetery in the country (Moon Cemetery)across the road from a house that obviously used to be a church. Vincent and Eleanor are my great great grandparents through their daughter Nancy, who married George Allen. If anyone who sees this has any additional information, especially about George's parents, Archibald and Margaret J Allen, I'd be thrilled. There was a stone in the same row as the McCoy's that said "Margaret J" but the last name couldn't be distinguished. I know that she died prior to 1868, because that's when Archibald remarried.
If I can be of any help to you with McCoy's, or Allen's, or Lane's, let me know and I'll be glad to tell you what I think I know.
